Patented May 14, 1940 UNITED STATES PATENT OFFICE FOUNTAIN PEN Maurice J. Waldinger, Flushing, N. Y.

Application July 13, 1939, Serial No. 284,237 4 claims. (o1. 12o- 42) My invention relates to fountain pens.

The object of my invention is to provide a receptacle for inksticks which when properly posiltioned and held in the barrel of a fountain pen,

5 will provide a chamber adjacent the inner Wall of the barrel, said inner wall serving to close the chamber at its outer side, said chamber being open at its end adjacent the pen section which carries the pen proper.

l0 A further object of the invention is to provide such a receptacle in the form of a cylinder having an unobstructed tubular passage therethru, and when placed in the barrel the inner wall of the barrel will serve to form the outer wall of the receptacle.

A further object is to provide a fountain pen of simple construction that may be made at a low cost, in which is located a receptacle for holding a plurality of inksticks in such a manner as to expose the ends only of the inksticks to view when the front pen section is removed, and which may be filled with said sticks directly after said pen section is removed.

A further object is to provide a fountain pen construction having a receptacle for inksticks, which is held in the barrel of the pen by friction only, and is open at one end only whereby the ends of said sticks only are exposed to the water used in making the writing uid.

Further objects and the advantages of the construction will now be stated.

Referring to the drawing which forms a part of the specication: n

Fig. l is a longitudinal sectional view of a fountain pen embodying my invention, disclosing self lling means therefor.

Fig. 2 is a longitudinalv sectional View of a pen construction, the pen section being removed from the barrel, thus exposing the receptacle to View.

Fig. 3 is a frontend view of the receptacle showing a construction in which a plurality of grooves are formed in its outer surface, each of which is formed for an inkstick to iit therein when the receptacle is in the barrel of a pen. Fig. 4 is a longitudinal sectional View thru the barrel of a pen, disclosing an exterior view of a receptacle having a longitudinally extending tubular passage therethru, and having its rear end fitted to slide in frictional engagement with the inner wall of the barrel to support it in the barrel in liquid tight relation, and reduced in diameter to form a space of annular form in which the inksticks may rest.

55 Fig. 5 is a front end View of the pen of Figure 4,

and disclosing the ends of inksticks carried by the receptacle. l

l0 indicates the barrel and Il the front pen section of the pen.

l2 indicates the receptacle which is cylindrical in form and provided with a cylindrical bore I3 which extends unobstructed thruout its length.

The receptacle its the inner wall of the barrel in liquid tight relation at its rear end I2.

When the receptacle is formed with slots l3-|3, etc., as illustrated in Figures 1 and 3, the inner wall of the barrel serves to close the outer adjacent sides of the slots and form separated cells into which the inksticks are placed, or any single cell may serve to hold one or more inksticks, depending upon the width of the cells or grooves, without increasing the depth of said grooves, as will be readily understood.

In the construction illustrated in Figures 4 and 5, the receptacle is mad-e by reducing the diameter of the cylinder to provide an annular chamber the outer wall of which is formed by the inner wall of the barrel, and this construction costs less to make than that of the grooved construction, and will hold a greater number of inksticks. indicated by I4.

In the construction illustrated in Fig. 1, the

rear end of the receptacle is extended in length and reduced in diameter to engage the open end of a sack portion l5, the construction being such that the removal of the end cap i6 will expose the extended portion of the receptacle, indicated by Il to permit attachment of said sack, or if desired, the entire body portion of the receptacle may be withdrawn from the barrel thru the rear end thereof, by using force suiicient to overcome the friction between the outer wall of the receptacle and inner wall of the barrel, as will be readily understood. When the sack section is used as a pump to fill the barrel with liquid, the usual air tube (not shown) is used in the manner well known to the art and therefore description of same herein is deemed unnecessary.

To those skilled in the art of making fountain pens no further description will be necessary for their complete understanding of the invention herein disclosed.

By its use a pen may be provided which will carry a large supply of inksticks which will serve to make ink over a long period of time, and by reason of the small area of inkstick exposed to the water in making a writing fluid, the water will not become overcharged with color or gum released in the disintegration of the inksticks.

Having thus described my invention I claim as new:

l. A fountain pen comprising a barrel and a pen-section connected therewith at its front end in separable relation, a receptacle for inksticks made in the form of a cylinder and having an unobstructed tubular passage extending therethru, and formed to provide a longitudinally extending chamber the outer side of which is closed by the inner wall of the barrel and an end of which is open adjacent the inner end of the pen-section and exposed to View upon the removal thereof from the barrel.

2. The construction defined in claim l, together with the receptacle having a rear end extension, a sack connected thereto, and a cap enclosing said sack and connected to the barrel; the construetion being such that the receptacle and sack may be removed from the rear end of the barrel.

3. The construction dened in claim l, together with said receptacle having a plurality of longitudinally extending chambers closed at one end and open at their opposite ends.

4. A receptacle for inksticks consisting of a cylindrical body formed to provide a tubular bore extending entirely therethru, one end of which is adapted to t the inner cylindrical wall of the barrel of a fountain pen, and a portion o1" reduced diameter extending the greater portion of its length and spaced from said inner wall a distance corresponding to the thickness ol' the inkstick to be used therewith, to provide a chamber an end of which will be in open communication with the reservoir of a pen in which it is placed.
